Calvin on Constantine

Calvin refers to Constantine only a handful of times in the Institutes , mainly in connection with the Donation. At one point, though, he comments him for restraining the intemperance of fourth-century churchmen (4.9.10):

“when the primary article of our faith was there in peril, and Arius, its enemy, was present, ready to engage any one in combat, and it was of the utmost moment that those who had come to attack Arius should be agreed, they nevertheless, feeling secure amid all these dangers, nay, as it were, forgetting their gravity, modesty, and politeness, laying aside the discussion which was before them (as if they had met for the express purpose of gratifying Arius), began to give way to intestine dissensions, and turn the pen, which should have been employed against Arius, against each other. Foul accusations were heard, libels flew up and down, and they never would have ceased from their contention until they had stabbed each other with mutual wounds, had not the Emperor Constantine interfered, and declaring that the investigation of their lives was a matter above his cognisance, repressed their intemperance by flattery rather than censure. In how many respects is it probable that councils, held subsequently to this, have erred? Nor does the fact stand in need of a long demonstration; any one who reads their acts will observe many infirmities, not to use a stronger term.”
